Double Eared ‘O’ Clamps
Connections on oil, fuel air and water lines
Heating and ventilating system in passenger cars and commercial vehicles.
Joints for pressurized liquid dispensing and material transfer systems
Selection of the correct size of O clip is essential. The inside diameter of the clip should be approximately 1/64” larger than the overall diameter of the tube plus fitting to obtain maximum joint efficiency.
To achieve the correct results as shown above it is recommended that pincers rather than ordinary pliers are used. Purpose designed O clip pincers with induction hardened jaws are available from Flexolite.
Advantages of O Clips vs. Worm Drive and Nut and Bolt Clips
1. The strength and performance of an O clip comes from the entire steel section and is not dependent on the single thread strength of a bolt or nut on a worm drive.
2. O clips are permanent and tamperproof. They must be destroyed to be removed.
3. Low unit cost from design simplicity.
4. Lower assembled system costs from faster attachment time.
5. Dimension tolerances are better and more consistent than conventional fasteners.
6. There are no areas of stress concentration. The heat treatment and manufacturing processes ensure uniformity of properties.
To achieve optimum performance:
1. Selection of the correct size of O Clip is essential
2. Correct method of closure must be employed.
Nut & Bolt Clips - Mikalor Supra W4 Heavy Duty Hose Clamp
Due to its revolutionary swivel bridge, the Supra W4 clamp can be mounted in the most awkward applications without having to remove the hose.
It can be opened and fastened again when in place without dislodging any other parts of the clamp, making assembly much easier.
The clamps have bevelled edges which protect the hose from damage.
The stainless-steel bolt, together with the captive nut and spacer system allow you to clamp the most demanding of hose assemblies. Supra W4 is a full stainless-steel clamp, destined for demanding applications where high corrosion resistance is vital. This top of the range heavy-duty clamp is ideal for demanding automotive applications.
The maximum application pressure can vary depending on the type of hose used and the geometry of the coupling.
Rubber Lined ‘P’ Clips
One of the most popular clips in the market. Most often they will be rubber lined using a 1.5mm thick E. P. D. M. rubber. The lined ‘P’ clip offers the user two advantages over the plain version. Firstly, the rubber protects the hose from the steel or stainless steel of the ‘P’ clip. Secondly, the rubber provides an anti-vibration / noise reduction through its cushioning effect. This has been found to be a great advantage in automotive applications, where rubber lined ‘P’ clips are used extensively and to great effect.
The E. P. D. M. rubber liner offers the user of the ‘P’ clip excellent heat resistance. From a freezing -40 deg C right up to 140 deg C, E. P. D. M. also offers excellent abrasion, weather, aging and ozone resistance as well as UV stability.
1/2" band width P clips sizes start from 3mm.
Fixing the clips can sometimes be challenging, however with the ½” band width design, difficulty is considerably reduced by the introduction of an elongated fixing hole on the front of the clip. This gives the user a far greater ability to locate the fixing screw / bolt than using 2 round holes or having the elongated hole on the back of the clip.
For strength, all sizes and band widths employ a strengthening ‘joggle’ located on the back of the clip. This means that where the rubber liner is flush with the clip, there is not just a simple ‘S’ curve in the metal, but a ‘joggle’ or finger that breaks this step in two, providing greater strength.
Worm Drive Clips
Tridon 350 series, 8mm band width full stainless-steel clips.
This U. S. A. designed worm drive hose clip, slips in where others are simply too big to fit. Employing a narrow 5/16” (8mm) band width and smaller screw size 1/4” (6mm), it can fit into places that the ‘traditional’ wide band clips cannot be used.
Manufactured from stainless steel, and using the ‘slotted’ band design, the clip offers the user a great deal of strength as ‘the entire band’ is caught on the screw threads and not just half. The housing is shorter, which gives the user a far greater size range that each clip can be used for and starts from a tiny 6mm (1/4”).
Installation torque 10 to 15 in-lbs (1.1 to 1.7 Nm)
